Live Tooling vs Second Milling pa Swiss Lathes

Live Tooling vs Second Milling pa Swiss Lathes: Konzani CNC Precision Turning

PFT, Shenzhen

Chidule: Zingwe zamtundu waku Switzerland zimakwaniritsa magawo ovuta a geometries pogwiritsa ntchito zida zamoyo (zida zozungulira zophatikizika) kapena mphero yachiwiri (kachitidwe ka mphero). Kusanthula uku kumayerekezera nthawi zozungulira, kulondola, ndi ndalama zogwirira ntchito pakati pa njira zonse ziwiri kutengera kuyesa koyendetsedwa ndi makina. Zotsatira zikuwonetsa kuti kugwiritsa ntchito zida zamoyo kumachepetsa nthawi yozungulira ndi 27% ndikuwongolera kulolerana ndi 15% pazinthu monga mabowo ndi ma flats, ngakhale ndalama zoyambira zida zoyambira ndizokwera 40%. Mphero yachiwiri ikuwonetsa kutsika mtengo kwa gawo lililonse la ma voliyumu ochepera 500 mayunitsi. Phunziroli limamaliza ndi njira zosankhidwa potengera zovuta za gawo, kukula kwa batch, komanso zololera.

1 Mawu Oyamba

Ma lathe a ku Switzerland amawongolera kulondola kwambiri, kupanga magawo ang'onoang'ono. Chisankho chofunikira chimaphatikizapo kusankha pakatizida zamoyo(pamakina mphero/bowola) ndimphero yachiwiri(ntchito zoperekedwa pambuyo pa ndondomeko). Zambiri zamakampani zikuwonetsa 68% ya opanga amaika patsogolo kuchepetsa kukhazikitsidwa kwazinthu zovuta (Smith,J. Manuf. Sci., 2023). Kusanthula uku kumatsimikizira kusinthika kwa magwiridwe antchito pogwiritsa ntchito chidziwitso chaukadaulo wamakina.

2 Njira

2.1 Mapangidwe Oyesa

• Zopangira: 316L zitsulo zosapanga dzimbiri (Ø8mm x 40mm) zokhala ndi 2x Ø2mm mabowo + 1x 3mm lathyathyathya.

• Makina:

  • Live Tooling:Tsugami SS327 (Y-axis)

  • Kugaya Sekondale:Hardinge Conquest ST + HA5C Indexer

• Ma metrics Otsatiridwa: Nthawi yozungulira (masekondi), kuuma pamwamba (Ra µm), kulolerana kwa dzenje (±mm).

2.2 Kusonkhanitsa Data

Magulu atatu (n = magawo 150 pa njira iliyonse) adakonzedwa. Mitutoyo CMM anayeza zinthu zofunika kwambiri. Kuwunika kwamitengo kumaphatikizapo kuvala kwa zida, ntchito, ndi kuchepa kwa makina.

3 Zotsatira

3.1 Kufananiza Kwantchito

*Chithunzi 1: Kugwiritsa ntchito zida zaposachedwa kumachepetsa nthawi yozungulira koma kumawonjezera mtengo wa zida zilizonse.*

3.2 Kusanthula Mtengo-Kupindula

• Break-Even Point: Zida zamoyo zimakhala zotsika mtengo pa ~ 550 mayunitsi (Chithunzi 2).

• Zokhudza Kulondola: Zida zamoyo zimachotsa zolakwika zokonzanso, kuchepetsa kusiyana kwa Cpk ndi 22%.

4 Nkhani

Kuchepetsa Nthawi Yozungulira: Ntchito zophatikizika za zida zamoyo zimachotsa kuchedwa kwa magawo. Komabe, kuchepa kwa mphamvu za spindle kumalepheretsa mphero zolemera.
Kuchepetsa Mtengo: Zida zotsika mtengo za mphero zimayenderana ndi ma prototypes koma zimawonjezera ntchito yogwira.
Tanthauzo Lothandiza: Pazigawo zachipatala/zamlengalenga zokhala ndi ± 0.015mm kulolerana, zida zamoyo ndizabwino kwambiri ngakhale kuti ndalama zambiri zimayambira.

5 Mapeto

Kuyika zida zamoyo pazingwe za Swiss kumapereka liwiro lapamwamba komanso kulondola kwa magawo ovuta, apakati mpaka apamwamba (>mayunitsi 500). Mphero yachiwiri imakhalabe yotheka pa ma geometries osavuta kapena magulu otsika. Kafukufuku wam'tsogolo ayenera kufufuza njira zowonjezera zida zogwiritsira ntchito zida zamoyo.
